Description
Technical field
The utility model belongs to component of machine technical field, is related to a kind of alignment pin, particularly a kind of ladder alignment pin
Structure.
Background technology
Alignment pin is to participate in the part that limitation is positioned the part free degree, is widely used in various industrial productions, in automobile
Combination assembling or performance test in largely used, ladder alignment pin is one kind of alignment pin, and it has two kinds or two
The location division of kind above different-diameter, so as to be positioned to multiple parts of different pore size simultaneously, such as to automobile side
Outside plate and reinforcing plate are enclosed when being positioned on fixture, and side-wall outer-plate and reinforcing plate share a master positioning pin, in the market
Ladder alignment pin relative adjustment can not be carried out to the location division of different-diameter, it is necessary to during adjustment position, above-mentioned side-wall outer-plate
It must be adjusted simultaneously with reinforcing plate, it is necessary to which mould changes hole position, costly, cycle length, and occurs and change hole phenomenon repeatedly.
Chinese patent (notification number：CN201714769U, publication date：2011-01-19) disclose a kind of staged positioning

When using this ladder locating pin structure, pin two can be avoided to be transferred to the envelope of pin two after extreme value and exceed the bag of pin one
Network, so as to cause scrape hole phenomenon occur when taking out the parts of positioning.
In above-mentioned ladder locating pin structure, above-mentioned b size is 1.4mm~1.8mm.Preferably, b size is
It is 1.6mm that the relative adjustment amount of 1.6mm, i.e. pin one and pin two is unilateral, the model that both diametrically opposite positions can adjust
Enclose for 0mm~3.2mm, so as to meet demand.
In above-mentioned ladder locating pin structure, one end that the pin two is connected with pin one is rear end, and the other end is
Front end, the front end of the pin two are additionally provided with guiding cone, and one end of the guiding cone is detachably connected with the pin two,
There is circular cone spigot surface on the other end outer peripheral face of the guiding cone.Guide effect is played by the guiding cone, conveniently originally
Ladder locating pin structure is inserted into the position components hole with positioning.
In above-mentioned ladder locating pin structure, it is tip that the guiding cone, which has one end of circular cone spigot surface, another
Hold as connection end, the connection end of the guiding cone has a cylindrical connecting portion and the connecting portion be plugged in it is described hollow
In groove, the tapped through hole along the radial direction of pin two is offered on the outer peripheral face of the pin two, is bolted with the tapped through hole
The end of jackscrew and the jackscrew can be resisted against on the outer peripheral face of the connecting portion.Adjustment pin one and pin two it is relative
During position, first unscrew jackscrew, pull down guide head, then loose bolts, put adjustment frock, be put into adjust pad, increased by side
Add opposite side to reduce the mode of pad and adjust the position of pin two, tighten bolt after being adjusted in place, remove frock and pad, fill
Upper guide head simultaneously locks jackscrew, completes whole adjustment process.
In above-mentioned ladder locating pin structure, alternatively, the guiding cone has circular cone spigot surface
One end is tip, and the other end is connection end, and the connection end of the guiding cone has cylindrical connecting portion, described hollow recessed
The madial wall of groove is periphery, has internal thread on the madial wall of the hollow recess, has on the outer peripheral face of the connecting portion
The external screw thread being engaged with the internal thread.It so can also realize being detachably connected for guiding cone and pin two, Er Qielian
Connect firmly, convenient disassembly.
In above-mentioned ladder locating pin structure, the rear end end face of the pin two is recessed with being respectively provided with the end face of pin one
